,ware, and it has for its object to provide means for taking and removinga measured quantity of glass from a mass or batch of molten glass metal, to transfer it to position over or in proper relation to aforming mold, to discharge said measured quantity into the mold, and to perform such functions continuously and uniformly during the operation of the apparatus.

In carrying out my invention I employ a measuring cu adapted to receive in its interior a pre-( etermined amount of molten glass by the employment of suction; means for removing any surplus metal from the cup and positively limiting its contents; means for reversing thecup from downward to upward position; means for lowering and raising it into and out of the batch; means for swinging the cup laterally into delivering position with relation to the mold; means for discharging the contents thereinto by reversing the cup; and, if desired, means for facilitatingsuch discharge by admitting air to the suction cavity.

In the accom anying drawings I have shown one form of apparatus adapted to perform the various functions necessary to carry out the different steps, and while such apparatus is adapted to give good results in practice, it will be readily understood that various other and different embodiments of the invention may be made by different mechanisms or constructions and I do not therefore wish to be limited to the exact or approximate construction or machine illustrated and hereinafter described.

Referring now to the drawings: Figure 1. is a plan view showing a portion of a rotating mold-carrying table and molds thereon, with each of which molds my invention is adapted to cooperate.

I have illustrated the apparatus as used in combination with that type of glass pressing machinery shown in my prior application for patent Ser. No. 259,754 filed May 10, 1905,

wherein an intermittently rotating table 2 provided with a circumferential series of molds 3 is constructed and arranged to bring each mold successively into stationary registering position witli a compressing plunger, and at the same time into charging position for filling the mold.

My present invention involves the use of an intermittently rotating framework adapted orarranged to cooperate as to its motions with the motions of said table and molds, and comprises a central supporting s indle or shaft 4 adapted to be intermittent y rotated. As shown, I actuate the spindle 4 by means of a shaft 5 geared in any suitable manner with the driving mechanism of the table 2, so that it will rotate the spindle 4 any pre-determined distance, as say onethird of a revolution, for each corresponding intermittent travel of the molds 3 from one position to another as from a to b; b to c;

the desired distance of travel ofthe cup from T the charg g position to the emptying position, as 0 early indicated in Fig. 1.

For the purpose of lowering and raising the measuring cup into the batch during the non-rotating period of shaft 4, I employ a.

cam 15 having a maximum" and minimum radius 16, .17, upon the periphery of which the shaft 4 is ste pe'd'. Cam 15 is rotated in conformity wit shaft 5 through shaft 18 and gearing 19, 20, whereby intermittent vertical motion will be im arted to shaft 4 and consequently to iall o the cups simultaneously as stated.

21 is a cupcarry1ng frame mounted on the upper end of shaft '4 and provided with a urality of, preferably 3, radial s ider arms 22, each of which carries a rotata le hollow spindle-23 mounted in suitable bearings and carrying at its outer end a cup 24 having a mersed into cavity 25 of suitable size to contain the desired quantity of glass. As shown, the cu is provided with one or a series of small air 'ports 26 communicating with the interior of hollow spindle 23,'said spindle being in communication with a central air exhaust pig?l 2'], as clearly shown in Figs. 5 and 6.

Fig. 5 the cu is shown in a reversed position for being led with glass, and upon spindle 4' bein lowered the cup will be imtl ie bath as shown in Fig. 2, while a valve 28 controlling the suction circulation may be used and will be automatically opened by reason of its stem 29 coming into contact with a stationary stop 30, open- 'ing the valve and permitting the exhaustof air from the hollow spindle to cause atmos- 1pfieric pressure on the surface of the glass to the cup. When s indle 4 is a ain raised by further rotation o cam 15, -va ve 28 will u beclosed by its spring 31, and spindle 4 will frame or base an the independent travel of rack 32, I havethen berotated, carrying the cu around to the discharging position over t e mold as shown in Fig. 1. It is desirable that the cup should be reversed to an upright osition during such swingin travel, and or such purpose I have provided a relatively movable-rack bar 32 engaging pinion 33 on hol low spindle 23, the rack bar having a roller or abutment 34 engagin groove 35 of a cam 36. Said cam is shdmg y mounted upon the stationary upperiportion'37 of the supporting in order that it may effect rovided with a crank disk 6 carrying a crank shown it as being arranged to ride up and down with the vertical travel of spindle4 and arms 22, for which purpose I employ pendent arms 38 havin upper and lower rollers -39, 40, enga ing a ove and below the cam as shown in ig. 12 or any equivalent mechanism. By this construction it will be seen that the cam rises and falls with the rise and fall of the cup spindles and cups, but being splined upon its supporting frame, is non-r0- tatable, and will therefore effect the independent rack rotation of each spindle 23 at the proper time. Cam groove 35, as shown in the diagram of Fig. 14-, -is so designed as to effect the turning overof the-cup immediately after it emerges upwardly from the bath, and commences to rotate, and the turning down of the cup immediately before it arrives at the charging position over the pressing mold.

In order to facilitate the discharge of the cupful of glass, I have provided means for adinittin atmospheric ressure to the interior of spindle 23 and the cup so as to destroy the partial vacuum or suction, and have shown each s indle 23 as provided with a port 41, normal y closed during. the nonrotating reversed position of the cup, but

adapted to register'with an inlet port 42 opening to the atmosphere, immediately uponthe cup being turned to upright position before the cup is turned over above the mold. The restablishment of atmospheric pressure in the interior of the hollow spindleand cu will, in combination with gravity, efiect t e complete discharge of the contents q downwardly into the mold.

It will be understood that the cubical contents of the cup may be exactly regulated to the desired amount by the size of the cavity, and for the 'urpose of positivel shearing off any surplus adhering glasal have provided a stationary knife blade or edge 43 mounted in arm 44 and extending laterally from the terminal bearing of spider arm 22, while the edge 45 of the cup is curved to a uniform radius, as indicated in Fig. 3. By this construction, when the cup is rotated after filling and its contents retained b glass will be sheared off, leaving an exactly measured quantity in the upwardly tilted it will be understood that the/pipe 27 is connected with any suitable air exhausting apparatus, and that the degree of the partial vacuum produced in hollow spindles 23 and the effect of suction, any surplus interior of the cups may be regulated to suit the existing conditions, as desired.

It will be understood that my gathering apparatus may be employed with any formof glass pressing mechanism, or in fact with any devices whatever wherein measured u'antities of'glass'are desired to be delivered rom time to time to a pressing or forming .further facilitate such discharge.

mold or a paratus of any character, irrespective 0 whether said mold is mounted upon a rotating table or otherwise; and also that any suitable actuating-or driving means may be employed, not necessarily in combination with the driving mechanism of the glass pressing or forming apparatus.

In the construction illustrated in the drawings wherein my invention is designed to tank extension, or receptacle, is then lowered into or upon the surface of the molten glass as in Fig. 2, whereupon the cup cavity will be filled by the effect of suction, the cup then being raised by cam-actuated s indle 4,

leaving it free from the glass and e ge of the The cup is then swung around laterally by rotation of spindlereceptacle, as in Fig. 5.

4 as described, during the first portion of which motion the surplus glass is sheared off by knife 43 and the cup is turned upwardly to an upright position as in Fig. 11 by means of the cam-controlled rack and pinion mechanism, the normal atmospheric pressure within the spindle and interior of the cup having been reestablished by register of the ports 41 and 42. Immediately before arriving at the discharging position over the mold the cup is reversed by the reversal of the cam groove 35, so that when the cup arrives at the end of its lateral swinging travel it will have been again reversed over the mold, into which the contents will be at oncedischarged. Such discharge will be facilitated asstated, by the equalization of the pressure in the interior of the spindle and cup, while the vertical drop of the cup due to cam 15, occurring simultaneously with the lowering of the next ensuing cup into the batch, will The emptied cup in its reversed position then travels around untilit is again in position for filling from the batch, when the operation is continued and may be carried on indefinitely.

It will be understood that any number of spider arms, spindles and cups may be used and I do not wish to be limited to three, the operation with a single arm and cup beingv in all respects the same as has been described.
